Do you mean selling listings (marketplace) or charging users for adding listings? I’ll release the paid listings extension in a few days, it’ll be possible to charge users for adding listings. Marketplace extension is also planned, but there’s no ETA.
It’s on the roadmap, but this extension will be paid – it’s pretty complex (managing commissions, payouts, refunds etc). Please feel free to post feature suggestions, do you mean creating a service like Fiverr (with digital services), or selling downloadable products?
HivePress will be integrated with WooCommerce for payments, but there will be a marketplace extension (for digital products or services only) instead of integration with existing marketplace plugins, this way I can be sure that it’s properly maintained and matches the HivePress API.
